Climate change and disaster risks

A 2013 report examined the relationship between disasters and poverty world-wide. It concludes that, without concerted action, there could be upwards of 325 million people living in the 49 countries most exposed to the full range of natural hazards and climate extremes in 2040.


Social Vulnerability and Environmental Disaster

According to author Daniel Murphy, different groups of people are able to adapt to environmental disasters differently due to social factors such as age, race, class, gender, and nationality.Murphy, Daniel; Wyborn (January 2015). "Key concepts and methods in social vulnerability and adaptive capacity". ''Research Gate''. Retrieved 2021-02-08. Murphy argues that while developed countries with access to resources that can help mitigate environmental disasters are often the countries that contribute the most to factors that can increase the risk of said disasters, developing countries experience the impacts of environmental disasters more intensely than their wealthier counterparts. It is often the case that the populations that do not contribute to climate change are not only in geographic location that experience more environmental disasters, but also have fewer resources to mitigate the impact of the disasters. For example, when Hurricane Katrina hit Louisiana in 2005, many scientists argued that climate change had increased the severity of the hurricane. Although the majority of the U.S. emissions that can contribute to climate change come from industry and transport, the people who were hardest-hit by Katrina were not the heads of large companies within the country. Rather, the poor black communities within Louisiana were the most devastated by the hurricane, despite not contributing as heavily to factors like climate change that likely increased the severity of Hurricane Katrina.

Mitigation efforts

There have been many attempts throughout recent years to mitigate the impact of environmental disasters.Murti, R. (2018, June 01). Environment and disasters. Retrieved February 24, 2021, from https://www.iucn.org/theme/ecosystem-management/our-work/environment-and-disasters Environmental disaster is caused by human activity, so many believe that such disasters can be prevented or have their consequences curbed by human activity as well. Efforts to attempt
